A coaxial cable formed on the periphery of the layer has been widely used for the transmission line for speech rate. In recent years, the aforementioned coaxial cable has been continuously reduced in diameter. For example, a very small coaxial cable having a center conductor diameter of less than 0.1 mm and a peripheral diameter of about .35 mm of the coaxial cable has been gradually used in electronic devices such as small notebook personal computers or mobile phones. 15 In these electronic devices, a plurality of coaxial wires are electrically connected to the liquid crystal display portion of the pen-type personal computer, for example, and the wiring and connection methods are complicated. In order to carry out the above-described complicated connection method in a simple and reliable manner, Japanese Laid-Open Patent Publication No. 2004-273333 discloses a method of holding a plurality of coaxial cables that are coaxially held in parallel on the same plane. 20, in the end portion of the coaxial cable of the conventional flat electric wire, the peripheral side insulating coating layer (outer cover) and the shielding layer are peeled off from the front end to the first predetermined length to expose the inner circumference side insulating coating After the layer (dielectric layer), a crimping portion is formed, and after the inner end of the crimping portion reaches a second predetermined length, the peripheral side insulating coating layer (cover) having a predetermined visibility is left on the front end side, and then peeled off.

However, a plurality of front-(four) shafts (four) have a high probability of dispersing at the ends of the aforementioned flat cable, and - _ is correctly maintained at the interval between the aforementioned electric vehicles, and also has a (four) joint crimping connection to the aforementioned flat The problem of reduced reliability of the connection at the green front end or when the shielding layer is grounded. For example, when the front end of the flat electric 1 is connected to the crimp pins of the aligned joints at equal intervals, the coaxial electric thinning is inserted into the crimping pin. Significantly becomes difficult. When it is worse, there is a problem that the aforementioned coaxial electric power is detached from the aforementioned crimping pin, resulting in poor energization.

' 5 Fig. 4 shows the enlarged view of the flat cable at the front end of Fig. 1. The 5th (5) 5 (8) diagram shows the processing of the flat electron microscope in Fig. 1. The preferred embodiment 10 of the present invention is characterized by the flat (four) embodiment of the present invention. In addition, the embodiment of the present invention is not limited to the invention of the patent scope of the present invention, and is also illustrated by the embodiment. The entire combination of features is not a necessary solution of the present invention. Fig. 1 is a plan view showing a flat electric red embodiment of the present invention, and Fig. 2 is a cross-sectional view taken along line AA thereof, and the top system is shown to constitute the aforementioned flat An enlarged view of the coaxial recording surface of the electric sign, and Fig. 4 shows an enlarged view of the front side of the flat electric winding. As shown in the second and second figures, the flat electric power is seen in the 100 series. A plurality of coaxial electric windings are arranged side by side at intervals, and the foregoing is a plurality of coaxial electric wires arranged side by side at a predetermined interval, and the two materials are fixedly arranged on the laminated sheet 50. That is, each coaxial electric iron Second Connected to the processing end side of the flat electric slow-end end processing portion K, the cross-shaped laminated sheet 50a is fixed to the full width of the electric winding, and the middle portion of the flat-shaped end processing portion κ is further The above-mentioned electric winding is fixed with a strip-shaped laminated sheet full width. 8 200805404 As shown in Fig. 3, the coaxial cable ι is configured to form an insulating material around the center conductor 11 formed by twisting a plurality of conductors. The dielectric layer 12 is formed, and a plurality of conductor core wires are laterally wound around the periphery of the dielectric layer 12 to form a shielding layer 13', and then formed on the periphery of the shielding layer 13 by an insulating material. The electric attraction iq becomes, for example, an extremely small diameter of about ο5 5 mm to 0.5 mm. The material of the dielectric layer 12 and the outer cover 14 can be, for example, a tetrafluoroethylene/perfluoroalkyl vinyl ether copolymer (hereinafter referred to as For rPFA"). As shown in Fig. 2, the laminated sheet 50 has a two-layer structure of the base layer 52 and the fusion layer 51. The base layer 52 is formed by processing, for example, a porous polytetrafluoroethylene (hereinafter referred to as "10" "EPTFE") film to a thickness of 3 Å μm to ΙΟΟμιη. The EPTFE film is obtained by perforating a material for processing a material (hereinafter referred to as "PTFE"), and is a fluorocarbon resin having a fine continuous porous structure. The EPTFE film has excellent properties such as heat resistance, chemical resistance, and weather resistance, and is excellent in durability even when processed into a sheet having a thickness of 3 〇 μm to 1 ΟΟ μm, and is excellent in flexibility and bendability. The fused layer 51 is formed on one side of the fixed coaxial cable 1A of the base layer 52, and is fused by a thick ΙΟμιη~50μηη composed of, for example, a tetrafluoroethylene/hexafluoropropylenediylene copolymer (hereinafter referred to as "FEp"). Floor. The fused layer 51 composed of the aforementioned FEP can be easily fused and fixed by the thermal fusion to the base 12 of the same 12-axis cable 10 and the base layer 52 composed of the aforementioned EPTFE. Further, *4 is fixed by thermal fusion bonding, so that a part of the laminated sheet 50 is subjected to laser processing after the fusion and fixing, and the portion can be peeled off. Here, the flat cable 1A will be described in more detail with reference to FIG. Cable end treatment for electrical connection is performed at both ends of each coaxial cable 10. At 200805404, the front end of the flat cable starts a predetermined distance, and the eight sheets 50, the outer cover 14, the shielding layer 13, and the dielectric layer are stripped and laminated. The center guide u is started by the root of the center conductor 11 by a predetermined distance. , the life of the layer 10, the cover layer 50, the outer cover 14 and the shielding layer 13 of the dielectric layer 12 = the portion of the toughness of the 12 layers of the toughness layer 12 begins to a predetermined distance d3, The layer 13 of the outer cover 14 is provided. The layer sheet is squeezing, and the inner portion of the cover layer (3) is left in the inner portion of the outer cover 14 and has a long strip shape S = 5〇a. In addition, the portion in the vicinity of the front end of the shielding layer 13 also remains on the flat-shaped laminated sheet of the outer cover 14 that spans the flat width of the flat-panel, according to the flat configuration of the above configuration, because it can be shielded The cover 残留 has a predetermined width remaining on the front end side, and the cover _ is exposed to the shielding layer 13 of the strip-shaped laminated slab 5〇a and the strip-shaped laminated sheet, so that most of the lateral winding of the shielding layer 13 can be prevented from being extremely thin. The conductor cores are scattered separately. Further, by the belt-shaped layered sheet 5Gb holding a plurality of coaxial cables 1 ′ at the front end of the flat electric winding, the coaxial buttons are not separated from each other, can be held at a predetermined position, and can be correctly maintained in the same manner as described above. The spacing between the shafts can also easily connect the signal wires to the contacts of the center conductor joints, and the connection work, and ground the strips to the shielding layer 13 of each coaxial cable 10 at the same time. To improve connection reliability and ease of operation when grounding is connected. Fig. 5 is a view showing the processing of the aforementioned flat cable 100. Further, in Fig. 5, only one end side of the flat cable 1 is shown, but the other end side is processed in the same manner. First, as shown in Fig. 5(A), FIG. 10, 200805404, 'the coaxial cable 1〇 is arranged neatly on the side of the fused layer 51 of the rectangular laminated sheet 50 (the inner surface side not shown), and is fused. The fusion layer 51 of the fixed laminated sheet 50 and the outer coaxial cable 1 are covered with a cover η. Next, as shown in Fig. 5(B), a long strip-shaped laminated sheet 50a and a strip-shaped laminated sheet 50b are formed using a laser processing machine or the like. In other words, for example, a carbon dioxide laser processing is performed across the flat cable at a predetermined width W1 from the front end side of the flat cable end by a predetermined distance (a distance at which the flat cable end portion is processed). The laminated sheet 50 of the predetermined width w1 and the outer cover 14 of each coaxial cable 1 are removed. Thus, the long laminated sheet 50a can be formed, and the shielding layer 13 of each of the coaxial cables 10 of the predetermined width w1 can be exposed. At this time, the width wb of the strip-shaped laminated sheet 50b is vacated from the front end side of the predetermined width w1 portion, and then the width of the flat cable is widened toward the front end side of the laminated sheet by a predetermined width w2. The carbon dioxide laser is etched to remove the laminated sheet 50 of the predetermined width w2 portion and the outer cover 14 of each coaxial cable 10. In this manner, the strip-shaped laminated sheet 50b can be formed, and the shielding layer 13 of each coaxial cable 1 of the predetermined width W2 portion can be exposed. Then, for example, YAG laser processing is performed across the front end side edge of the strip-shaped laminated sheet 50b across the flat cable, and the shielding layer 13 of each coaxial cable 10 is cut. -0 Next, as shown in Fig. 5(C), the front end of each coaxial electric gauge 10, that is, the belt-like layer 10b, can be removed by extracting the abundance sheet 50c' on the front end side of the flat electric ram. The front end side outer cover 14 and the shielding layer 13 are further provided. In this manner, the dielectric layer 12 of each of the coaxial cables 1B on the front end side of the strip-shaped laminated sheet 50b is exposed. 11 200805404 Then, as shown in Fig. 5(D), the position of the predetermined distance from the front end of the flat electric winding is performed toward the flat front end side by a predetermined width boundary 3 across the flat cable, for example, carbon dioxide laser processing. The dielectric layer I? of each of the coaxial galvanometers is removed, and the center conductor I]'5 is exposed. In this way, the aforementioned flat cable 1 can be completed. Further, as shown in Fig. 5(E), it is also possible to provide two pieces of metal, for example, a slightly strip-shaped ground strip formed of a secret steel, which is exposed to the upper and lower laminated sheets 50a and Each of the coaxial laminated electron microscopy of the strip-shaped laminated sheet has a cover layer 13' and a flat cable which is firmly fixed to the shielded buckle 10 of each coaxial electric cable and the like. In this case, the shielding layer 13 between the strip-shaped laminated sheet member and the end portion of the flat electron microscope is sandwiched by the outer cover 14 or the strip-shaped laminated sheet 5〇b, and the grounding strip 30 is fixed to the grounding strip 30. When the shielding layer 13 is on, it does not deviate from the position in the long-term direction of the electric field and does not deviate from the position of the length 15 of the electric gauge when the heating solder is melted, and the position of the grounding strip on the shielding layer 13 does not occur. (4) In the case of poor size, a flat wire with a high accuracy of the grounding strip 3G can be provided. • By using the above type, since the spacing between the coaxial cables 10 can be suppressed: the fluctuations can be made, the electrical connection between the signal line connection and the ground connection of the plurality of coaxial cables 10 can be easily performed simultaneously. Further, although the above-described embodiment is a single-sided laminated sheet structure, it is also possible to provide a double-sided laminated sheet structure in which another laminated sheet 50 is sandwiched between the upper and lower sides and laminated and fixed. &. Further, although the structure of the (4) > material 5G is only fused to the electric end portion, the structure of the 2008 20080404 in which the laminated sheet 5 is fused across the entire length of the electric field can be similarly used. Further, in the flat cable 100 of the present embodiment, the number of the coaxial cables 10 fixed by the ground bar 30 is not particularly limited. For example, in a mobile phone, a flat 5 flat cable composed of 20 to 5 coaxial cables is used, but a notebook PC uses a flat cable composed of a plurality of coaxial cables, and The flat cable 100 used in the present invention can be used in any of the following. Next, an embodiment of the present invention will be described. (Example) 10 A dielectric layer 12 composed of PFA having a thickness of about 50 μm was provided on the periphery of a center conductor π formed by combining seven conductors of a diameter of 25 μm, and 20 diameters of 3 〇 μηι were wound around the periphery of the dielectric layer 12. The conductor core wire is formed to form a laterally wound shielding layer 13 as an outer conductor layer, and the 40 micro-coaxial cable 10 is fixed to the laminated 15 sheet 50a of a thickness of 8 μm formed by the aforementioned EPTFE at a cable pitch of 〇4 mm. After the 50b is single-sided, the flat cable 100 is formed, and the coaxial cable 10 is provided with a cover 14 made of PFA having a thickness of about 35 μm on the outer periphery of the shielding layer 13. According to the flat electric switch 1Q0, when the end processing is performed and the center line η signal line of each of the coaxial electric contacts is connected and grounded to, for example, a joint contact, the coaxial cable 10 can be prevented from being dispersed. The aforementioned connection work is performed simply and surely. The above description has been made on the embodiment and the embodiment of the present invention, but the flat cable 100 of the present invention has at least the end portions of the plurality of coaxial cables 10 fixedly arranged side by side on the laminated sheet 50, and is used for electrical purposes. The % of the connection coaxial cable 10 is referred to as the intermediate portion of the flat-end processing end processing portion, and a strip-shaped laminated sheet 50 is formed to extend across the entire length of the electric cable 13200805404. That is, the intermediate portion of the plurality 10 of the end portions of the flat cable 1 is exposed by the end of the cable, and the intermediate portion of the plurality 10 of the end portions of the flat cable is formed by the smashing wg J-axis cable to form the agglomerated sheet 50b. _It is not easy to ride the Wei-Lei end, but it can maintain the accuracy of the above-mentioned coaxial surface clearance, and can easily and complicatedly perform the aforementioned complicated electrical connection work.
